Using this Injen cold air intake is easy. First, make sure your engine is cool. Then, follow the included instructions to remove the old air intake system. Install the new Injen intake using the provided stainless - steel hardware and urethane couplers. It's a straightforward process that doesn't require any special tools or aftermarket tuning. When it comes to maintenance, regularly check the 8 - Layer oiled cotton gauze air filter. If it's dirty, clean it according to the cleaning instructions. Also, keep an eye on the intake tube and housing for any signs of damage or debris. Avoid driving through deep water without the optional snorkel system (sold separately) to prevent water from entering the intake. This will help ensure the long - lasting performance of your Injen cold air intake.
